The platform currently offers two modes for users: standard and experimental. The standard mode operates on Gemini 2.5 Flash, providing reliable performance for common tasks. The experimental mode, however, utilizes the more powerful Gemini Pro, which unlocks advanced capabilities. This latter option even permits users to upload visual elements like screenshots or wireframes to guide the AI-driven interface generation process, leading to more refined outcomes.

Stitch leverages Google’s AI research to interpret natural language descriptions and transform them into functional design elements. This technology represents a step forward in making digital product design more accessible. The goal is to reduce the initial effort in setting up UI structures, allowing creators to focus more on user experience optimization from the start.

How Does Stitch Work?

Using Stitch is a relatively direct process. You begin by selecting the type of project you intend to create, such as a dashboard, a general web application, or a mobile app interface. Following this selection, you describe your vision for the UI, detailing aspects like color schemes, layout preferences, or specific user experience goals. Effective prompt engineering can greatly influence the quality of the output.

Once you have input your detailed description, Stitch initiates the generation process. It produces HTML, CSS, and editable components based on your prompt. These generated elements are not final; you can customize them further, adding new features or tweaking existing ones as needed to align with your project’s specific requirements and achieve visual consistency.

The tool aims to understand context and intent from your prompts. For instance, instead of just saying “a blue button,” you might specify “a primary action button with a modern flat design, using a vibrant blue, placed in the bottom right corner.” The more context Stitch has, the more closely the initial output will match your expectations, speeding up the design iteration speed.
